One Kilojoule is 1,000 Newton Metre, ie the work done or energy transfered to an object when a 1,000 Newton force acts on it over one metre. It can also be defined as the heat energy dissipated by a current of 1,000 amperes passing through a one Ohm resistor for one second
One BTU is the energy required to warm 1 avoirdupois pound of liquid water by 1 degree Fahrenheit, at one atmosphere. The Btu (3.9°C) uses the calorie value of water at the temperature of its maximum density
